  • Prepaid SIM cannot connect to any network abroad (roaming enabled, multiple countries tested)

    Hi,

    Thanks for the reply.

    To clarify the situation: I’m not fully sure whether the SIM was successfully activated in Germany. A friend brought it to Vietnam for me and mentioned that the KYC (Video-Ident) was completed.

    However, the current behavior is:

    • the SIM can detect available networks (e.g. Viettel, Mobifone)
    • but it cannot connect to any network at all (no service / registration fails)

    Based on this, I believe the issue might not be related to datapasses (since even basic network registration fails), but rather a possible activation or provisioning issue.

    Could you please check if the SIM is fully activated and allowed to register on foreign networks?

    Phone number: +49 xxxxxxx234

    Thanks!

  • Prepaid SIM cannot connect to any network abroad (roaming enabled, multiple countries tested)

    Hello,

    I’m currently experiencing an issue with congstar prepaid SIM cards when roaming abroad.

    Situation:

    • The SIMs are used outside Germany (tested in Vietnam and China)
    • Devices: iPhone and Android (multiple devices tested)

    Observed behavior:

    • Roaming is enabled on the device
    • Available networks (e.g. Viettel, Mobifone, etc.) are visible
    • However, the SIM cannot connect to any network (“No Service” / registration fails)
    • Manual network selection also does not work
    • Same issue occurs across multiple countries

    What I have already tried:

    • Enable/disable roaming
    • Restart device
    • Manual network selection
    • Test SIM in different devices

    Question:

    • Is roaming enabled for congstar prepaid SIMs in countries like Vietnam or China?
    • Could there be a roaming block or missing activation on the SIM/account?
    • Does the SIM need to be activated in Germany first before roaming works?

    Any help would be appreciated. Thank you!
